Pardon my ignorance here, but why is a "double-install" procedure required for these two versions? I liked how with the 3.1 versions you could just use the floppy disks and not have to take the time to install 3.1 to some hard disk first.
If it's to do with the BoingBags, then surely there could've been some way of automating their installation alongside copying files off the CD in one go? Using LhA or what have you.
Also, I wonder if the Amiga Forever OS3.9 will be supported?
